That's great photos. Nice shots and good luck with the seeds. What's the size of the bulb ? Thanks shoggoths, the bulbs are about 3/8" in diameter. I took some leaf pullings from these plants on Oct. 1 and the plants seemed to abruptly stop making new leaves at that point, so i don't know if the leaf pullings were a shock to their system or not. Here are some of the plantlets produced from those leaf pullings, varying in size from very small to not too bad. Since i'm not sure how much these are all going to grow before they go dormant, i've been feeding the plantlets as much as possible, just so that they may make a substantial sized bulb to hopefully sustain them through a dormancy period. dvg

How do you keep your gravel from getting all mossy and compacted? I find after about 3 months it gets bound together by algae and moss.

Haha, i'm not really too sure myself why there is less moss on the surface of these plant's growing media. It might be because the plants are kept so dry during most of the year, that the moss doesn't really get much of a foothold in there with them. dvg

Here's an update on these P. heterophylla leaf pullings. The leaves were pulled on Oct. 1, and only two months later, these plantlets are growing quite quickly on their own roots. Some of the larger clumps of these are already putting out the mature summer-type leaves, with the smaller plantlets getting ready to start theirs as well. It's going to be interesting to see how large of a bulb these plants will be able to produce before they go dormant, but in the meantime they are being heavily fed and are also being kept on the damp and humid side. dvg

Great job DVG,
Those are really nice plants. Also, your method seems to work really well.
The plants are on your windowsill. It must help to trigger dormancy. Do you also give them artificial light (sorry if you already answer this question, I've reread the other post quickly but do not have see the answer) ?
Surely a must try plant ! Do you consider it an easy one ?

Do you consider it an easy one ? Thanks Shoggoths, The picture was shot close to window for better color rendering, but these plants do grow in the basement under grow lights. The question of what triggers these plants in and out of dormancy is still a curious one for me. These plants don't seem to stay in their active growth state for very long and when i took leaf pullings from the active plants, they ceased further noticable growth at that point. And once they are in dormancy, it would be nice to know the trigger to induce them back to the growing stage again. These plants aren't hard to grow when they are growing, but some growers do lose them in their dormancy period. I keep these plants bone dry in that stage and have been able to keep them going through a few cycles, but with the few extra plants made available from the leaf pullings, i'll now be able to experiment with and better observe these plants and their personal cultivational preferences . dvg

I used to have a colimensis which was a very strict dormancy plant. It went on a winter dormant, summer growth cycle, I presume daylength mediated.

P. colimensis is another tricky Pinguicula species to try and keep in cultivation. I was able to get strikes on some P. colimensis leaf pullings right around the same time i did the P. heterophylla pullings, so i'll be able to experiment more with both of these species. dvg

Sadly, Lloyd's P. colimensis has now expired. He gave it to me and it was doing wonderfully through the summer but as soon as it started going dormant it got hit by crown rot and was gone in a couple of weeks. I tried to salvage some leaf pullings but they went brown in days, so I think it must have been the nematode-induced crown rot I've read about.
I just got the AIPC monograph on Pinguicula and it's very good. Lots of interesting species to look out for, and I think it's time to take a trip to the aquarium shop for some different substrates.

Nice work on those hetero leaf pullings Doug. Hard to believe from their size that they are only 2 months old - I guess its important to keep those little bellies filled with food I have had similar experiences with Drosera seedlings - in fact regular feeding is a must for many of the more difficult ones to ensure survival beyond the 1st year. Looking forward to your future updates. Rob

Thanks Rob,
I was really surprised by how much of a difference feeding seedlings as well as plantlets from leaf pulls would make, and it makes a real difference.

Okay, almost a month later and these plantlets from pullings are still growing quite well on top of their 7" diameter pot. As long as they continue to put out new growth, they'll be kept in the same growing conditions. dvg

These two dormant bulbs have finally started to awaken and appear to each be pushing out a flower. I tried to force these into active growth by wetting their growing medium a few months back, but it didn't work out at all. I then allowed the media to completely dry out and waited for them to resume growing again, once they were ready. dvg

They seem very similar to medusina. I tried jump-starting my medusina with some water a few weeks ago with no results.
